The present invention relates to an improvedv rake for general purposes, but usea'ble particularly for raking lawns, to gather up dead grass or'leaves thereon. v

The invention has more particular reference to" that species of rake, in which the I toothed rake head will automatically clear itself of accumulated grass and weeds on the back stroke and which assumes aproper '10 operating positionwith respect to the handle the rake, head toautomatically assume operating position promptly at the beginning' ofv the forward stroke.

My object is to gei'ierally improve upon "the end of the return stroke and at the be:

structures of this class by providing one which is characterized by greater simplicity,

I du'r'ability, dependability, and one which is such as to obviate the utilization "of easily breakable springs and equivalent elements,

suchas are ordinarily employed.v I

Other features and. advantages of the in- 3 vention willlbecome apparentffromjthe, fol-1 lowing description and drawings.

In the drawings, the reference numeral 5 designates a handle providedon its forward endwith-a fork6, the ends of the arm POI- tions of which terminatein bearings 7, extending inwardly as shown inFigure 2, and disposed in abutting relation with the opposite ends of .the tubular bearing 8, carrying a centrally arrangedlongitudinally curved lifting and drag finger 9. A pivotpin 'o' r'bolt 10 passes through these parts and also I ment and being engageable withi thetground.

through the laterally. di'r'ecte'dfendportions 11', forming pivot lugs or'ears for 'the' toothect rake head 12. Incidentally, the central portion'oftheback of{ the head is raised as at 13, and' the endlportions of this are utilized in the formation of the pivotears'll.

Normally, the relationship of parts is as shown in Figure 1, during-whic'h time it is assumed that the'rakeis being drawn toward I 'theuser-in the direction of theiar'row A. 6D]

This is the forward stroke. At" this time, the-head l2 assumes a positionat right angles to the fork 6, and the liftingfinger 9 ex I tends between the teeth and simplydrags alongv the surface, The forward curvature 5 of the lower pointed end facilitates the dragging action. When, however, the rake 'is' moved-in. the return direction, as indicated by the letter B, in Figure 4,,the parts become collapsedand assume, the folded; relationship here represented. The rake head slidesalong the surface a'ndthe lifting fin'gerdrags. At

ginning of the next forward stroke, thelower end of the curved finger 9 literally digsiinto the ground and operates 'as'a fulcrum lever in lifting the end portion of the handle up the reader to understand the inventionand i the features thereof. Consequently a more inor changes in shape, size, and re-'f-,-

arrangement of details coming within the field of invention claimed may beresortedfl to," in actual practice ifdesired.
